Bitcoin Mining

What Is Bitcoin Mining?

Chances are you hear the phrase “bitcoin mining” and your mind begins to wander to the Western fantasy of pickaxes, dirt and striking it rich. As it turns out, that analogy isn’t too far off.

Bitcoin mining is performed by high-powered computers that solve complex computational math problems; these problems are so complex that they cannot be solved by hand and are complicated enough to tax even incredibly powerful computers.

KEY TAKEAWAYS Bitcoin mining is the process of creating new bitcoin by solving a computational puzzle.Bitcoin mining is necessary to maintain the ledger of transactions upon which bitcoin is based.Miners have become very sophisticated over the last several years using complex machinery to speed up mining operations.

Digital Korokoza: The dark side of crypto mining

It’s diamonds that are forever, not your computer hardware. A few weeks ago, I was pleasantly surprised when I received a 5-minute voice note from an enterprising young man that I know from my local church. The Chemical Engineering graduate innocently elaborated his plan of crypto mining on any high-powered computer I may own.

Essentially, he was politely requesting to digitally “korokoza” in my backyard, as he claimed that his software would quietly and unobtrusively crypto mine in the background. Fortunately, being a man of virtue, he was not wielding any weapons or hurling any threats nor insults as you normally see from everyday Korokozas. He was most sincere and humble in his ignorance. Naturally, I had to respond with a voice note twice as long explaining why I had to courteously decline. 

“Korokoza is a slang word in the Shona language that refers to an illegal miner or illegal mining activity.”

Cryptocurrency has been and stil…

Beating the 2020 Crash In 5 Steps

For years to come, we’ll be talking about the “Stock Market Crash of 2020.”

This has been one of the worst months for the Dow which included the three worst point drops in U.S. history.

We are headed, quite possibly, for a depression. 

I’ve said for a long time, dating all the way back to 2002 when I predicted , that the biggest stock market crash in U.S. history would happen sometime around 2016.

What I didn’t see at the time of my prediction were two things: 

1.Quantitative Easing

In 2008, after the weapons of mass financial destruction exploded (mortgage-backed securities and collateralized debt obligations), and the world economy nearly collapsed, Fed Chairman Ben Bernanke did what he believed the Fed should have done in 1929: print more money.

Bernanke was driving into the future, but looking into the rearview mirror.

As the old saying goes, “Generals prepare to fight the …

Be careful, most YouTube ripping sites are now logging user data

We are always saying this but it’s true. Data is expensive in Zimbabwe which is a little odd considering YouTube, one of the most data-intensive sites out there, has been consistently one of the most visited sites in the country. The clever ones have found ways to enjoy their YouTube clips without having to visit the site every time. They use YouTube rippers.

What’s a YouTube ripping site?

Using sites known as YouTube rippers results in massive data savings. Let’s say you and your friends enjoy a show like Comic Pastor’s monthly awards, Bus Stop TV’s regular skits or even Jah Prayzah. Instead of buying data to go on YouTube every time you want to watch:

You just visit a ripper site like flvto.biz or 2conv.com.You paste the URL of the video you want in a provided field click convert or download and the video is saved to your device in your preferred format.

Now you can watch it as many times as you want on your phone or tablet. You ca…

Britbox is coming to South Africa next week Friday

In February of this year, we learnt that the popular streaming platform BritBox would be available to South Africans, which almost certainly means some Zimbos will have access too. South Africa will be the fifth country to get the nod after the United States, Canada, Australia and of course the United Kingdom itself. We now have a launch date, 6 August 2021.

What’s BritBox and how much will it cost the South Africans?

BritBox is a joint operation run by ITV and BBC. The former is a free to air commercial operator kind of like the eTV of Britain and the latter is a public owned broadcaster along the lines of ZBC although there are some differences. The streaming platform is a way for them to extra money and make themselves relevant in the Netflix era.

The two operators already have their own Video on Demand offerings on their websites. ITV’s hub has premium and ad-supported tiers while the BBC’s iPlayer is funded by TV licences and doesn’t feature…

Archived WhatsApp chats will now remain in the dark, where they belong

I am pretty sure I am preaching to the choir here but anyway over the last day or so I have noticed that WhatsApp archived chats are no longer popping up in my inbox even if a new message comes in. This is something that I didn’t pay too much mind to until I started paying attention to the shift that happened in a recent update that moved Archived chats to a tab at the top of my WhatsApp.

Well, it looks like WhatsApp has made it so that chats that are sent to the archive folder will now remain there even if you get a new message from that chat or group.https://platform.twitter.com/embed/Tweet.html?creatorScreenName=chitungwie&dnt=false&embedId=twitter-widget-0&features=eyJ0ZndfZXhwZXJpbWVudHNfY29va2llX2V4cGlyYXRpb24iOnsiYnVja2V0IjoxMjA5NjAwLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X2hvcml6b25fdHdlZXRfZW1iZWRfOTU1NSI6eyJidWNrZXQiOiJodGUiLCJ2ZXJzaW9uIjpudWxsfSwidGZ3X3NwYWNlX2NhcmQiOnsiYnVja2V0Ijoib2ZmIiwidmVyc2lvbiI6bnVsbH19&frame=false&hideCard=false&hide…

If humans aren’t designed to eat meat because we have to cook it, why do we cook anything?

We don’t have to cook meat. If you went out and hunted it yourself, butchered it and ate it immediately, you wouldn’t need to cook it (unless it was particularly tough). Some Inuit and Sami people still live their lives that way.

But the meat we eat isn’t killed and eaten immediately. It might be weeks since slaughter before it ends up on your plate, and during that time, there is the opportunity for bacteria to flourish. We need to cook most commercially-produced meat, because of that risk of bacteria.

Vegetables are a different matter; some of them such as cassava, potatoes and red kidney beans, must be cooked to destroy the poisons in them. And some are just too tough to eat raw, they must be cooked to break down the fibres and make them digestible.

Econet set to adjust promotional bundle prices

Econet Wireless Zimbabwe will this week review the price of its promotional voice, data and SMS bundles, according to a notice issued to customers by the mobile operator.

The adjustment, which sources in the company said will be around 20 percent, will come into effect on Thursday, July 8, 2021, and is largely seen as a response to escalating operational costs.

The Postal and Telecommunications Regulatory Authority of Zimbabwe (Potraz)’s recent sector report said mobile network operators’ running costs grew by 34.1 percent in the first quarter of 2021 to $7.6 billion, up from $5.7 billion in the previous quarter.

“Staff costs, depreciation and bandwidth costs continued to constitute the bulk of mobile network operating costs,” the regulator said in the report released last month.6

Potraz noted that the continued rise in prices of goods and services in the country, in line with movement of the foreign exchange market, was not helping m…
